Effect of mechanical milling and cold pressing on co power

Author: Bolokang, AS ; Phasha, MJ ; Motaung, DE ; Bhero, S Date: 2012 Cold pressing (CP) of the amorphous-like Co powder suppressed most of the XRD peaks, in particular the peak along (100) plane. The DSC curve of unmilled CP Co powder has shown a distinct sharp exothermic peak at 615◦C. Upon annealing at 700◦C, ... Read more
Effect of pressure on the metastable phase formation of equilibrium immiscible Ti-Mg system studied by ab initio technique and mechanical milling

Author: Phasha, MJ ; Kasonde, M ; Ngoepe, PE Date: Nov 2008 The CSIR is exploring options of mixing titanuim with lighter metal elements such as magnesium and aluminium to help decrease energy consumption. Titanium and its alloys are very important materials from both technological and scientific point ... Read more
Effect of thermal treatment on mechanically milled cobalt powder

Author: Bolokang, AS ; Phasha, MJ ; Camagu, ST ; Motaung, DE ; Bhero, S Date: Mar 2012 Stabilization of the metastable FCC phase has been achieved after 10 h milled Co powder sintering at 1400 °C. Phase identification of the Co powders was performed by the X-ray diffraction analysis, while the microstructural analyses were ... Read more
Ti-Pt Alloys form mechanical milling

Author: Nxumalo, S ; Chikwanda, HK ; Machio, Christopher N Date: Dec 2009 The high temperature ß-TiPt phase has been shown to undergo a martensitic transformation upon quenching to room temperature. The martensitic transformation results from a transformation of the parent B2 cubic structure to the martensitic B19 ... Read more
