WebJul 26, 2011 · In some processes this method is still utilized today. The Mohs scale consists of 10 minerals, ordered from hardest at 10 (diamond) to softest at 1 (talc). Each mineral can scratch those that fall below it in the scale hierarchy. The Mohs scale is not linear; the difference in hardness between 9 and 10 is significantly more than that between 1 ... WebMar 28, 2024 · The strength of metal materials can be improved through the following five methods: 1) Conducting a heat treatment process, such as quenching, tempering, normalizing, etc., based on the required performance and structure. 2) Surface shot peening. 3) Grain boundary strengthening. 4) Dislocation strengthening.
