New multicomponent Hf-based bulk metallic glasses have been developed starting from a Hf-rich Hf-Cu-Ni-Al alloy containing Cu, Ni and Al in proportions near those in well known Zr-Cu-Ni-Al BMGs. In order to increase the glass forming ability and the stability of the glassy phase, selected elements with negative heats and volumes of mixing ΔHmix and ΔVmix respectively were added. The selective additions depress the liquidus temperature as measured by differential thermal analysis (DTA) and increase the width of the supercooled liquid region, ΔTx=T x-Tg between glass transition (Tg) and crystallization (Tx) temperatures.
