In this work. the DD98M single crystal superalloys were brazed to themselves using a Pd-Si composite filler. The effect of brazing temperature and soaking time on the microstructure and mechanical behavior of the joints was studied. The microstructure and phase constitution in the joint were identified by the SEM and EDS analysis. https://safeersappliancers.shop/product-category/rangemaster-infusion-inf110dffss-110-dual-fuel-stainless-steel-chrome-trim/
