Methods for comparing the hardness of minerals and metals, and testing methods using diamonds.

Methods for comparing the hardness of minerals and metals, and testing methods using diamonds.

[Reproduction of Private Spring Preparatory School Lecture 1] Comparing Hardness: It's About Scratching! An explanation of metal hardness and a testing machine using diamonds.

From now on, I will borrow this space for a while to establish the Spring Preparatory School. Difficult subjects will be learned after entering a regular university, so here is a preparatory school where you can study casually. Typically, preparatory schools tend to have a gray mood, but in that regard, our school, aptly named Spring, offers a warm and pleasant atmosphere. Feel free to enjoy a few minutes of lessons in any style you like. That said, since we are receiving payment for the newspaper, let's start with a solid and serious discussion. *You can view the detailed content of the article in the PDF. For more information, please feel free to contact us.*

Learn about methods for measuring hardness and the types, roles, and importance of testing machines.

[Reproduction Private Spring Preparatory School Lecture 2] The national standards for power test machines, testing methods, and reference pieces are firmly established in JIS!

The method of measuring hardness can now be done using testing machines as mentioned above, but what does the term "hardness" generally express? It often represents not only the degree of resistance to diamond but also characteristics such as being difficult to deform, hard to cut, prone to wear, and so on, which are commonly referred to as the mechanical properties of materials represented by the term hardness. Therefore, there is also a term "spring hardness," and nowadays, it conjures the image of a very strong and elastic spring. *For detailed content of the article, you can view it in the PDF.

The evolution from horse-drawn carriages to automobiles and the development and modernization history of Japanese spring manufacturing.

The evolution from horse-drawn carriages to automobiles and the development and modernization history of Japanese spring manufacturing.

[Reproduction of Private Spring Preparatory School Lecture 5] The rickshaw is also a benefactor for the spring industry! It also discusses the modernization of the spring industry.

The birth of Japan's spring industry, as mentioned last time, began with carriage springs. Even today, about a hundred years after the Meiji era, spring manufacturers are making a living from automobiles, which are a transformation of carriages, so we must be grateful to carriages. So, when did carriages, which have been so beneficial to Japan's spring industry, arrive in Japan? According to records, they began operating as public carriages in the Keihin area in 1869 (the second year of the Meiji era), and by the seventh year of Meiji, they were also operating in Tokyo. The number of these public carriages was only 319 in the eighth year of Meiji, but by around the time of the Russo-Japanese War, 38 years later, it had increased to 6,631, which is quite significant. *For more detailed information, please refer to the PDF.

The advancement of automobile development and spring technology, as well as innovations in materials and research progress in the late Taisho period.

The advancement of automobile development and spring technology, as well as innovations in materials and research progress in the late Taisho period.

[Reproduction of Private Spring Preparatory School Lecture 7] The Emergence of Automobile Springs, the Great Earthquake, and the Major Advancement of Automobiles! The late Taisho period was an era when spring research became full-fledged.

In the previous discussion, we talked about the beginning of domestic production of spring materials in the early Taisho period, and how various manufacturing facilities and testing equipment were established, leading to a significant leap forward. This time, let's continue with the late Taisho period. By the early Taisho period, the main railway lines were mostly constructed, and streetcars were operating in large cities; however, it was still the era of horse-drawn carriages and rickshaws. During this time, bicycles and automobiles were rapidly gaining popularity. However, while bicycles were becoming common, automobiles were still vehicles for the privileged class, and it was not yet the case that everyone could have one, as is the case today. Nevertheless, as vehicles changed, it was inevitable that springs would also change, and spring manufacturers had no choice but to start producing automobile springs. *For more detailed information, please refer to the PDF.

Difference between premium liquor and hard steel: Changes in properties brought about by alcohol content and carbon amount.

Difference between premium liquor and hard steel: Changes in properties brought about by alcohol content and carbon amount.

[Reproduction Private Spring Preparatory School Lecture 26] As the amount of carbon increases, both tensile strength and yield point increase!

In the last class, we learned that the properties of steel can change dramatically with just a tiny difference in carbon content, comparable to a speck of dust. For example, even when comparing mild steel and hard steel, the difference in carbon content is only about 0.5%. Just like how premium liquor with a higher alcohol content is more expensive, steel also becomes more costly with a higher carbon content. However, the difference between mild steel and hard steel is not just a matter of the distinction between second-class and premium liquor. *For more detailed information, please refer to the PDF.

The relationship between yield point, tensile strength, strength, and hardness in steel tensile testing.

The relationship between yield point, tensile strength, strength, and hardness in steel tensile testing.

[Reprint Private Spring Preparatory School Lecture 27] Explanation of the load and elongation diagram in the tensile test of steel!

Today, let's study a little about the terms that express the strength and brittleness of steel. The strength of steel is usually understood through a tensile test. As you may know, in a tensile test, a tensile load is applied along the axis of the specimen until it fractures, and during this process, the relationship between the load and elongation, as well as the reduction in cross-sectional area, reveals the elastic limit, yield point, tensile strength, elongation, and reduction of area. *For detailed content of the article, you can view it in the PDF.

The relationship between ski downhill courses and the cooling rate of steel quenching.

The relationship between ski downhill courses and the cooling rate of steel quenching.

[Reproduction of Private Spring Preparatory School Lecture 30] Explaining what happens when the cooling speed from high temperatures is changed!

Steel has a stepchild called carbon, and when it is rapidly cooled from a high temperature, it does not undergo a straightforward transformation, but instead becomes a solid solution of carbon in alpha iron. This quenched structure is called martensite. The microscopic structure of martensite is needle-like and very hard. For example, the hardness of martensite in spring steel is about 700 on the Brinell hardness scale. However, not all steels achieve this level of hardness. *For more detailed information, please refer to the PDF. Feel free to contact us for further inquiries.*

Differences in types of spring steel wire and manufacturing processes.

Differences in types of spring steel wire and manufacturing processes.

[Reprint Private Spring Preparatory School Lecture 36] An explanation of the differences between the brothers of spring steel wire and their growth processes!

I taught you how to read JIS standards, but take another look at the spring steel wire. Indeed, thinner wires have greater tensile strength than thicker ones. The thickest one is the 12 mm "spring carbon steel oil-tempered wire," which has a tensile strength of 120 kg. Looking at it this way, we can define spring steel wire as having a diameter of 12 mm or less and a tensile strength of 120 kg or more. Why is strong steel wire used for springs? It is because the cross-sectional shape is uniform and the material length is long, making it convenient to mass-produce springs with consistent characteristics. *For more detailed information, please refer to the PDF.
