Influences of hot-isostatic-pressing temperature on microstructure, tensile properties and tensile fracture mode of Inconel 718 powder compact

Powder bed binder jet printed alloy 625: Densification, microstructure and mechanical properties

“…These precipitates have script morphology and exist throughout the entire interdendritic area. We assume that these precipitates are the Laves phase, which is the final solidification product of Ni-based superalloys [15]. Additionally, one EDS scan spectrum and results (relative error of EDS can be as high as 2%) of the as-received feedstock powder are given in Table 1, respectively, showing agreement within the relative error with the manufacturer-provided values (Table 1).…”

A novel near α-Ti alloy prepared by hot isostatic pressing: Microstructure evolution mechanism and high temperature tensile properties

“…In our previous work, a monolithic Ti6Al4V disk was successfully fabricated using NNS-HIP and the relative density of the disk reached 99.5% [24]. So far, HIP processing of Ti6Al4V [25][26][27], TiAl [28][29], Nickel-based superalloy [30][31][32][33][34], and Al-based powders [35], etc., has been studied. However, up to now, to the best of authors' knowledge, there was no literature reported on the fabrication of a near-α high temperature titanium alloy (the series of Ti-Al-Sn-Zr-Mo-Si) by HIP process and the study of high temperature mechanical performance was rarely involved.…”

An investigation of densification behavior of nickel alloy powder during hot isostatic pressing

“…Mainly studies regarding hipping of nickel alloys powder are concentrated on studying the mechanical properties and microstructure of hipped parts [8,9]. Recently, Chang et al [8] studied the effect of hipping temperature on the microstructure and tensile properties of Inconel 718 powder compact.…”
