text: "Additive manufacturing, e.g. by laser powder bed fusion (LPBF), is very attractive
for lightweight constructions, as complex and stress-optimised structures integrating
multiple functions can be produced within one process. Unfortunately, high strength
AlZnMgCu alloys tend to hot cracking during LPBF\r\nand thus have not so far been
applicable. In this work the melting and solidification behaviour of\r\nAlZnMgCu
alloy powder variants with particle surface inoculation was analysed by Differential
Fast\r\nScanning Calorimetry. The aim is to establish a method that makes it possible
to assess powder modifications in terms of their suitability for LPBF on a laboratory
scale requiring only small amounts of powder.\r\nTherefore, solidification undercooling
is evaluated at cooling rates relevant for LPBF. A method for the\r\ntemperature
correction and normalisation of the DFSC results is proposed. Two ways of powder
modification were tested for the powder particles surface inoculation by titanium
carbide (TiC) nanoparticles:\r\nvia wet-chemical deposition and via mechanical
mixing.\r\nA low undercooling from DFSC correlates with a low number of cracks
of LPBF-manufactured cubes. It\r\nappears that a reduced undercooling combined
with reduced solidification onset scatter indicates the\r\npossibility of crack-free
LPBF of alloys that otherwise tend to hot cracking."
