Effect of aluminum substitution on the reflectance spectra of hematite [PDF]
Hematite and aluminous hematite were synthesized and the diffuse reflectance spectra were recorded for the region between 0.35 and 1.20 microns. Results show that the near-IR based minimum for the aluminous hematite is shifted longward by about 0.02 ...

steel research international, EarlyView.In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can
