Analysis of mixing and alloying processes by mechanical alloying.

Raney-nickel Catalysts Produced by Mechanical Alloying

Raney catalysts were prepared by a combination of mechanical alloying and leaching as an alternative in the synthesis of Raney-Nickel catalysts. Binary Al-Ni and ternary Al-Ni-Fe alloys with nominal compositions Al65Ni35, Al75Ni25, Al65Ni30Fe5, Al75Ni20Fe5 (in atomic percent), were processed from pure elemental powders; they consisted mainly of the intermetallic B2 AlNi phase. Aluminum was sele...

Fe-doped SnO2 obtained by mechanical alloying

In this work, iron-doped SnO2 powders were prepared by two methods: mechanical alloying and mechanochemical alloying with successive thermal treatment. The influence of different milling conditions such as ball to powder weight ratio, milling time, rotation velocity of supporting disc and the type of iron starting reactive and their Fe concentration on the structural and magnetic properties of ...

Structure and properties of Al67Ti25Fe8 alloy obtained by mechanical alloying

Purpose: The goal of this work is to investigate structure and properties of powdersAl67Ti25Fe8 alloys obtained by mechanical alloying. Design/methodology/approach: The powders of the Al67Ti25Fe8 alloys were obtained by mechanical alloying method in a planetary Fritsh Pulverisette 5 mill. The changes of the constitution phases were tested by means of the X-ray diffractometer. The microscopic ob...
