Abstract
This paper reports complementary experimental and theoretical investigations focussed on the laser milling of theamorphous alloy Zr41.2Ti13.8Cu12.5Ni10Be22.5, also known as Vitreloy 1, in ambient air, using 220 ns pulses. Theconducted experiments showed that the formation of crystalline precipitates...
