Invar Characteristics and Machinability of Mn-Ge-Misch Metal Alloys

Numerical Studies on the Magnetism of Fe-ni-mn Alloys in the Invar Region *

By means of self-consistent semi-empirical LCAO calculations we study the itinerant magnetism of (Fe 0.65 Ni 0.35) 1−y Mn y alloys for y between 0 and 0.22 at T = 0 K, neglecting only the transverse spin components. We find that the magnetic behaviour is quite complicated on a local scale. In addition to ferromagnetic behaviour, also metastable spin-glass-like configurations are found. In the s...

0 ” Cold Melting ” of Invar Alloys

An anomalously strong volume magnetostriction in Invars may lead to a situation when at low temperatures the dislocation free energy becomes negative and a multiple generation of dislocations becomes possible. This generation induces a first order phase transition from the FCC crystalline to an amorphous state, and may be called " cold melting ". The possibility of the cold melting in Invars is...

Machinability of Experimental Ti-Cu Alloys

This study is an investigation of the machinability of experimental Ti-Cu alloys (2, 5, and 10mass% Cu) as new dental titanium alloy candidates for CAD/CAM use. The alloys were slotted with a vertical milling machine and carbide square end mills under two cutting conditions. Their machinability was evaluated through cutting force using a three-component force transducer fixed on the table of th...

Machinability of experimental Ti-Ag alloys.

This study investigated the machinability of experimental Ti-Ag alloys (5, 10, 20, and 30 mass% Ag) as a new dental titanium alloy candidate for CAD/CAM use. The alloys were slotted with a vertical milling machine and carbide square end mills under two cutting conditions. Machinability was evaluated through cutting force using a three-component force transducer fixed on the table of the milling...
