  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."
