title: [The effect of vacuum vibration investing and vacuum mixing on the properties of "LAW-Modellguss investment" and the fit of cast structures from cobalt-chromium-molybdenum alloys. 1. Technologic-experimental tests].
abstract: Using materials-scientific test methods, the author studied the effect of vacuum mixing and vibration on the setting and the thermal expansion and contraction behaviour of the investment compound "LAW-Modellgusseinbettmasse" as well as on its hardness and structure after setting. The results obtained show that vacuum processing may considerably improve the properties which are of importance in model casting.
