tensile test
61gauge length — used in the mechanical testing of steel, it is the length marked on the parallel portion of a tensile test piece from which the elongation is measured …
62proof stress — the stress that will cause a specified small, permanent extension of a tensile test piece. Commonly the stress to produce 0.2% extension is quoted in N/mm2 for steel. This value approximates to the yield stress in materials not exhibiting a… …

69Peening — is the process of working a metal s surface to improve its material properties, usually by mechanical means such as hammer blows or by blasting with shot (shot peening). Peening is normally a cold work process (laser peening being a notable… …
70Hydrogen embrittlement — (or hydrogen grooving) is the process by which various metals, most importantly high strength steel, become brittle and crack following exposure to hydrogen. Hydrogen cracking can pose an engineering problem especially in the context of a… …
