Use of DICTRA® simulations to support carbide particle growth study in NbC-Ni cemented carbide
(2020-07-24)
Carbide particle growth observed in a NbC-12%Ni (mass percent) sample sintered at 1420 °C was discussed using DICTRA® simulation of spherical particles immersed in a Ni matrix. It is possible to describe the liquid formation ...
Formation of Cu-rich Nanoprecipitates in Cu Containing Pearlitic SGI
(2020-11-29)
The presence of Cu-rich nanoprecipitates in a pearlitic spheroidal graphite (ductile) cast iron alloyed with 0.82 wt%Cu was studied. The size and distribution of the precipitates were examined by transmission electron ...
Effect of MAG welding transfer mode on sigma phase precipitation and corrosion performance of 316L stainless steel multi-pass welds
(2020-08-07)
The effect of multi-pass MAG welding transfer modes on the sigma phase precipitationand corrosion performance of AISI 316L thick plate were investigated. The evolution of themicrostructure was examined by optical and ...
