Abstract: Surface brittle fracture of metals is inhibited by impinging on the surface of the metal an intense pulsed beam of charged particles, neutral particles or radiation while the metal is maintained at a temperature at least above its nil ductility temperature. Energy from the pulsed beam creates high thermal gradients and concomitant high stresses which in turn effect high plastic strain in the surface region and produce a unique fine subgrain structure on and immediately underneath the surface. The treatment enhances the resistance of the metal surface to brittle fracture and results in decreased cracking, delaminating and grain lifting.
Abstract translation: 当金属保持在至少高于其零延展性温度的温度下时，通过在金属表面上撞击带电粒子，中性粒子或辐射的强脉冲束来抑制金属的表面脆性断裂。 来自脉冲光束的能量产生高热梯度和伴随的高应力，这又导致表面区域中的高塑性应变，并在表面上并紧接在表面之下产生独特的精细亚晶格结构。 该处理增强了金属表面对脆性断裂的抵抗力，并导致破裂，分层和晶粒提升减少。
