X‐Ray Spectroscopic Study of the Band Structure of Some Binary Ti Alloys

Abstract

The A1L-and K/3-emissiod bands of noble and several transition metal 293 aluminides have been investigated in (1). In the spectra of the alloys two peaks a r e observed. It was also established that the V K P -bands from the alloys V Rh, V Pd, V Ir, and V Pt a r e split into two main subbands (2). In (3) the TiKP -bands from some intermetallic Ti-Cu compounds have been investigated. It was found the valence band of these compounds consists of two subbands.This report is a continuation of the investigations (3) with the aim of studying the energy band structure of alloys of titanium with the transition metals and silver.The alloys under investigation had the following composition: Ti+90% N i , Ti2Pd, Ti Pt, TiCu, TiCu X-ray analysis. Excepting Ti Ag (4), all investigated alloys contained one phase.The fluorescent X-ray KP -emission bands of titanium were recorded photographically in the second order reflection from a bent quartz crystal ( l O i 1 ) . The films were photometered point-by-point and the results were averaged.and Ti Ag. The crystal structure of the alloys was tested byThe experimental results a r e presented in Fig. 1 and 2. The following experimenta l results should be pointed out:1. TiKP -spectra from binary titanium alloys with Cu, Ag, Pd, and Pt consist of two subbands (labelled A and B in the figure). The short-wave subband A coincides by its energetic position with the maximum of the pure titanium KP -band. Table.

“…17 High energy resolution XES enables to probe the ligand environment of a metal of interest. 12,[18][19][20][21][22] Access to the ligand orbital is obtained by ionizing the core electron and measuring the following valence-to-core transition. This decay channel involves the valence electrons of the ligands and therefore provides information about the highest occupied electronic levels in matter.…”
