Mechanically driven b.c.c. TiCr alloy and its hydrogen solubility

Hydrogen sorption properties of Ti–Cr alloys synthesized by ball milling and cold rolling

“…Within experimental errors, strain and crystallites sizes are identical for all alloys. The lattice parameters determined in the present study are slightly bigger than the ones reported by Yabe and Kuji [22] but agrees quite well with those measured by Takeichi et al [18].…”

“…1), it can be seen that after 5 h ball milling, the diffraction peaks of the C14 and C15 Laves phases disappeared and Ti-Cr alloys with a BCC structure are formed. This behaviour agrees with previous reports on ball milled Ti-Cr alloys [18,19,22]. Table 4 reports the lattice parameters, strain and crystallite size of each alloy.…”

“…It is therefore difficult to form exclusively metastable BCC phase by rapid quenching of TiCr 2 . Nevertheless, it has been shown that for Ti-Cr binary alloys, with 60-66 at.% of Cr, a metastable BCC phase can be obtained by ball milling [12,[18][19][20][21][22]. However, no studies reported if cold rolling could also lead to the formation of metastable Ti-Cr BCC phase at room temperature.…”

Formation of a continuous series of Ti–Cr–Fe bcc solid solutions in a powder mixture ground in a planetary-ball mill

“…The paper [4] examines the grinding of titanium and chromium for 90 h in a NEV-MA8 high-energy vibration mill (Nissin-Giken, Japan). No performances of the mill are provided in [4].…”

“…No performances of the mill are provided in [4]. It is indicated that grinding a mixture of titanium and chromium containing more than 50 at.% Cr leads to the formation of a chromium-enriched bcc phase; should a mixture contain more than 50 at.% Ti, two bcc phases form, one being rich in titanium and the other in chromium.…”
