Journal ArticleDOI
An Investigation of the use of Stearic Acid as a Process Control Agent in High Energy Ball Milling of Nb-Al and Ni-Al Powder Mixtures
Cláudio José da Rocha,Ricardo Mendes Leal Neto,Valéria S. Gonçalves,L.L. Carvalho,Francisco Ambrozio Filho +4 more
TL;DR: In this article, the use of stearic acid as process control agent in milling Nb-Al and Ni-Al powder mixtures was investigated, and the aim was to find a optimum quantity of that additive concerning milling action and decreased contamination.
Journal ArticleDOI
Synthesis of a nanocrystalline composite W–25 wt.%Ag powder by high energy milling
Franciné Alves Costa,A.G.P. Silva,Francisco Ambrozio Filho,Uilame Umbelino Gomes,Francisco Antonio Vieira +4 more
TL;DR: In this article, the effect of high energy milling on a 25-wt.% Ag pseudo-alloys was investigated, where phase dispersion, evolution of the shape and size of the particles during milling and the influence of strain on the crystal structure were investigated.
Journal ArticleDOI
Preparation of Metal Matrix Aluminum Alloys Composites Reinforced by Silicon Nitride and Aluminum Nitride through Powder Metallurgy Techniques
Everthon Rodrigues de Araújo,Marcio Marcelo Sampaio de Souza,Francisco Ambrozio Filho,Cezar Henrique Gonzalez,Oscar Olimpio de Araújo Filho +4 more
TL;DR: In this article, a vibratory type SPEX mill, cold uniaxial compaction and vacuum sitering was used to investigate the influence of the particulate phase in the microstructure and mechanical properties of the composites obtained.
Journal ArticleDOI
Influence of the heat treatment on the microstructure of AISI T15 high speed steel
Rejane A. Nogueira,Odília C.S. Ribeiro,Maurício David Martins das Neves,Luis Filipe C.P. de Lima,Francisco Ambrozio Filho,Delmonte N. Friedrich,Lourival Boehs +6 more
TL;DR: In this article, the influence of quenching temperature on the mean austenite grain size and size distribution and volume fraction of the primary carbides, MC and M 6 C, in AISI T15 samples prepared by hot isostatic pressing and liquid phase vacuum sintering was quantitatively investigated.
Journal ArticleDOI
