Abstract
Inventia se refera la o metoda pentru determinarea fragilitatii otelurilor slab aliate tratate si sudate în vederea stabilirii daca otelul respectiv poate sa nu sa fie utilizat în constructii metalice sudate. în acest scop se utilizeaza niste epruvete care sunt supuse unor cicluri de încalzire între 1000 si 1350 degree C, similare operatiunii de sudare, dupa care epruvetele respective sunt supuse unui tratament termic de detensionare la niste parametri corespunzatori otelului utilizat apoi, metalografic, se determina cantitativ constituentii formati si functie de acesti constituenti se poate preciza daca materialul respectiv poate fi utilizat sau nu în scopul propus.
