| Whether the properties of Ti alloy by additive manufacturing is better than that of traditional castings and forgings is the focus of researchers' attention, and there is an urgent need to carry out systematic detection and evaluation methods. The shortcomings in the basic theoretical research on material strain detection and related formability of Ti alloy components by additive manufacturing and the research status at home and abroad were mainly summarized. Combined with the research experience, the research hotspot of additive manufacturing at the present stage and the digital speckle strain accuracy detection were generalized. Then, the feasibility of applying digital speckle correlation method to additive manufacturing strain detection was reviewed, and the key scientific problems and solutions of DSCM method in constructing detection and evaluation system were put forward. The experimental scheme of DSCM strain detection and forming limit visualization in additive manufacturing was discussed, which was divided into digital speckle measurement system, method and theory of strain measurement, realization mechanism of strain compare and forming limit visualization. Finally, the research progress in this direction was concluded, and the development prospect and main development direction were prospected. |
