摘　　要：对 Ni- Al系粉末压坯激光反应烧结的初步研究表明 ,利用激光反应烧结能够弥补一般激光烧结受试样尺寸的限制。并因其点火时间短、反应层层递进、扩展等特点 ,使得烧结后试样整体组织和性能均匀 ,且易得到网状结构和理想的产物。The preliminarily experimental results of laser reactive sintering of Ni-Al powder compacts show:The limitations of the normal laser sintering by sample size can be compensated with laser reactive sintering,and dud to the distinctive characteristics of laser reactive sintering such as a very shot ignition time and layer-by-layer propagation of the reactive,the homogeneous microstructure and properties,as well as a net-shape structure and ideal products can be obtained.
