The subject of hardness scale conversion encompasses a wide range of important elements. Toughness - Engineering Stack Exchange. for this question: "What is the difference between strength, hardness and toughness in materials?" i have searched and have found these following definitions Strength refers to resistance to At what temperature do I risk altering the structure of steel?. If I have structural or tool steel that has been treated to some standard (ASTM, SAE, ISO -- e.g., for hardness) but I don't know the details of the treatment, is there a "safe" temperature below w... mechanical engineering - How do I determine what hardness to change the .... The steel tire could easily be any hardness you want.
It would be poor judgement to mess with the rolling element bearing hardness. The heat-treatment has been developed over decades. This perspective suggests that, one factor is the residual compressive stresses developed on the surface ( by New Departure years ago) to significantly extend fatigue life. materials - Durometer and Shore - Engineering Stack Exchange. Similarly, can someone help me understand durometer and shore hardness testing with relation to rubber hardness?
My understanding is durometer measures hardness, shore is a different type of scale. What is the significance of brittle materials and why do we use them?. We have studied that cast iron which is a brittle material is used in automobile cylinder block, head, housing flywheel etc.
If it is a brittle material then why it is used there? Another term that is confusing me is hardness. How hardness is related to brittleness. If a material is strong and hard, will it be brittle?
How do you plot a relation between hardness and strain. What is the most corrosion resistant 55HRC stainless steel?. Equally important, 55 HRC is a very high hardness, even for steels. In relation to this, ideally the corrosion resistance of the steel would have to match AISI 316L or be even better. Qenched stainless steel can go to 55HRC.
Difference between Stiffness (K) and Modulus of Elasticity (E)?. In Solid Mechanics, We can relate these K=AE/L. I am confused in these. Both resist deformations when load is applied on it. Is K constant like E is constant.
Another thing which is confusing is hardness which is the same (resists deformation on application of load). Shore durometer type D to brinells - Engineering Stack Exchange.
