Investigation was made of effect of preplastic deformation for unexplosive and explosive treatments on strength, surface residual stress and hydrogen embrittlement of the specimens.
研究了预塑变对爆轰处理和未爆轰处理样品的强度、表面残留应力、氢脆敏感性及其关系的影响。

They both involve heating, rather than burning, waste until it breaks down into a flammable mixture of carbon monoxide and hydrogen, called syngas, and residual char, ash or slag.
The large welding current caused the formation of quenched martensite and the high residual stresses in the welding zone, resulting in the increase of zinc sensitivity of hydrogen attack.
