    The effects of hydrostatic pressure on the compressive mechanical behavior of L12 Al3Ti-based intermetallic

    A Mn-modified Ll2 Al3Ti-base intermetallic was subjected to compressive deformation at room temperature under superimposed hydrostatic pressures up to 1000 MPa. It is found that its yield strength is essentially ...
