The Reason Metals Need To Be Hardened And Tempered For Higher Quality

heat-forged

Metals need to be hardened for an improvement in their mechanical properties, as well as an increase in the level of hardness, producing a tougher, sturdier item. Alloys are heated above the critical transformation temperature for the material, then cooled rapidly enough to cause the soft initial material to transform to a much harder, stronger structure. Alloys may be … Read moreThe Reason Metals Need To Be Hardened And Tempered For Higher Quality

What Happens During The Annealing Process?

heat-forging

Annealing in metallurgy and material science is a heating treatment that modifies the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness. In the annealing process, atoms migrate in the crystal lattice and the number of dislocations decreases, leading to a change in ductility and hardness. This process … Read moreWhat Happens During The Annealing Process?
