摘要: The jump frequency of Cd tracer atoms in pure and Al-doped b-Mn was determined from measurements quadrupole relaxation using the method perturbed angular correlation gamma rays. containing about 4.5 at.% Al had an activation enthalpy 0.67(3) eV. In at 950 K, a factor 8 larger than value 9.2 MHz alloy. Information also obtained sluggish kinetics a-Mn to polymorphic transformation.
