In situ strengthening of titanium with yttrium

Microstructure and Texture of Al&ndash;2Si&ndash;<i>x</i>Sn (<i>x</i> = 0, 4, 8 mass%) Alloys Processed by Equal Channel Angular Pressing

“…In the last two decades the main efforts have been focused on Cu or Al systems, with body centred cubic (bcc) second phase such as Nb or Ta, i.e., CuX (where X = Nb, Ta, Cr, V or Fe), 28) having the objective of increasing the mechanical strength of these alloys. In the 1990's, some studies started with hexagonal (hcp) metals including TiY, 9,10) MgTi, 11) AlTi 12) and Al Mg, 13) however, the understanding of the fundamental mechanisms controlling the mechanical deformation and the microstructure evolution is still unclear.…”

Microstructure-Strength Relationship of a Deformation-Processed Aluminum-Magnesium Composite

“…According to previous study on CU-X [2-10] and other DMMCS [11][12][13][14][15][16], the larger the deformation ratio, the higher the ultimate tensile strength. Tensile tests were done for the A1-Mg composites to see if a similar phenomenon exists here.…”

“…Some recent studies of Ti-Y [13][14][15][16], Mg-Li-Ti [17][18][19], A1-Ti [20] have shown hexagonal close packed (HCP) metals' potential application in DMMC'S. The HCP metals will develop a e 1010> wire texture when axisymmetrically deformed.…”

“…In order to extend use of the deformation processing to non-cubic systems, researchers have studied hexagonal close packed (HCP) metals [13][14][15][16][17][18][19][20]. The candidate metals should possess good ductility, mutual immiscibility and roughly similar mechanical properties.…”

Al-Ca and Al-Fe metal-metal composite strength, conductivity, and microstructure relationships

“…Frommeyer et alia [18] and a Au-Ag DMMC studied by Russell et alia [19] have been reported. The typical microstructure for fcc/fcc DMMC's is cylindrical second phase filaments embedded in the matrix.…”
