以Ti40Zr25Ni3Cu12Be20大块金属玻璃为研究对象，研究了关键工艺参数对点焊组织和力学性能的影响。点焊缝尺寸和晶化体积分数在控制接头力学响应中以复杂的方式相互作用。冷却速度的评估表明，结晶体积分数在热影响区比熔合区更容易达到显著水平。还确定了焊缝在玻璃环境中保持的条件。电阻点焊是连接大块金属玻璃的一种可行技术。
Ti40Zr25Ni3Cu12Be20bulk metallic glass was used to study the influence of key process parameters on the spot welds microstructures and mechanical properties. Spot weld size and crystallized volume fraction were found to interact in a complex fashion in controlling the joint mechanical response. Assessment of cooling rates indicated that crystallized volume fraction was more liable to reach significant levels in the heat-affected zone than the fusion zone. Conditions for which the welds sustained a glassy environment were also determined. Resistance spot welding was found to be a feasible technique for joining bulk metallic glasses.
