“…Additionally, Jiang [8], Gong [9], Galli [10] and Vaidya [11] have also developed finite element techniques to predict the residual stress fields in dissimilar brazed joints with a limited number of validation tests performed on brazed specimens. Despite initial research into developing finite element models to predict the stress state in dissimilar brazed joints, at present there are no techniques which take into account all the factors described in the following section.…”

“…And unlike the normal glass, the CAS glass-ceramics, a heterogeneous composite material, consists of β-wollastonite crystal phase with a lower coefficient of thermal expansion (CTE) and glass phase with higher coefficients of thermal expansion. Any mismatch between the coefficients of thermal expansion of the constituents in a composite material may generate residual stress called "thermal mismatch" stress (TMS, or "pseudomacrostress" termed by Cullity) upon cooling or heating again in service [2,6,7] . In the ordinary course of events, this thermal mismatch stress is several times bigger than the thermal residual stress mentioned above, even differ in one or two orders of magnitude.…”

“…It is also seen that the graded interlayer produced a joint without microcracks or porosities. It was demonstrated previously [9] that in general, the occurrence of microcracks in joints was a result of large stresses developing due to the CTE mismatching between the materials being joined. However, in the present study, CTE would be expected to be changed slowly because of gradient compositions within layer by layer.…”

“…However, the residual thermal stress induced during cooling, a decisive factor in the joining strength in the graded interlayer, can always occur and is hardly effectively and accurately measured by x-ray and other conventional methods. [8][9][10][11] In this work, we developed a new approach of SPS by the use of 9 graded interlayers to join MoSi 2 to 316L stainless steel. The joint with excellent properties was achieved at moderate temperatures.…”
