Abstract

Conform inventiei, aparatul include un batiu, prevazut cu mijloace de solidarizare a unei epruvete, al carei al doilea capat este solidarizat de un arc elicoidal de fprma cilindrica si lucrînd prin compresiune. Arcul elicoidal este prevazut cu un subansamblu de mofidificare a tensiunii saler si conectat la un mijloc de masurare a deformarii. Epruveta este dispusa într-un cuptor prevazut cu mijloace de modificare a pozitiei sale pe verticala. Se utilizeaza, în special, în metalurgie.According to the invention, the apparatus includes a bar provided with means for joining a specimen, the second end of which is solidarised by a cylindrical cylindrical spiral spring and working by compression. The helical arc is provided with a saffler mofidization subassembly and connected to a deformation measuring means. The specimen is disposed in an oven provided with means to modify its vertical position. It is mainly used in metallurgy.
