Abstract

Prior work on laser additive manufacture has shown that it is only possible to produce crack free components in TiAl when using a supplementary heat source to control the cooling rate. In this work the LENS process was used to produce crack free TiAl parts without using a secondary heat source by manipulating the laser focus position.
