Effect of depth implantation of lanthanum on the oxidation of Fe80Cr20 based …
The aim of this study is to investigate the effect of depth implantation of lanthanum on the oxidation of Fe80Cr20 alloys. Intermetallic FeCr was developed by mechanical alloying technique with milling time 40 h and 60 h respectively and followed by hot compaction process at a temperature of 1273 K and pressure of 25 MPa. The specimens were implanted with Lanthanum dopant with doses of 10…

Preparation of nanocrystalline y-Alumina using ultrasonic technique
The γ-alumina powder is a potential material for washcoat application. This paper shows the preparation of γ-alumina using ultrasonic technique in order to obtain nanocrystalline of γ-alumina powder. The 50 gr of the γ-alumina powders was treated in the 250 gr ethanol solution using ultrasonic technique within 10, 20, 30, and 60 minutes, respectively. The process of sonication was set at th…
