Povzetek

Mnogo raziskav cepilnega krhkega loma je pokazalo, da so normalne napetosti v trdnostno neenakih zvarih v dobri korelaciji z lomnim obnašanjem krhkih cepilnih materialov. Namen raziskave je najti tiste mikrostrukturne mehanizme, ki vodijo do cepilnega krhkega loma. Raziskave centra makroskopskih rečnih strug pokažejo pri večjih povečavah drobno razvejanost rečnih strugic. Te rečne strugice lahko zajemajo eno ali več cepilnih faset in predstavljajo iniciacijske točke krhkega loma trdnostno neenakih zvarov.
