摘　　要：通过对HRBF400、HRBF500细晶粒热轧钢筋进行多种溶液的应力腐蚀试验，探索性衡量细晶粒热轧钢筋的应力腐蚀敏感性。进行不同的试验条件下进行试验的对比，摸索钢筋进行应力腐蚀的试验条件。对细晶粒热轧钢筋在使用过程中，不用考虑其氢脆敏感性。细晶粒热轧钢筋对NH4SCN、NaCl、NaHSO4溶液无应力腐蚀敏感性。Stress corrosion experiments of hot rolled ribbed bars of fine grains HRBF400, HRBF500 in several solution are studied, exploring to measure the stress corrosion of the materials. And to explore the proper experiment conditions for the sress corrosion experiments of hot rolled ribbed bars. In conclusion, the hot rolled ribbed bars of fine grains are not demanded to consider the hydrogen embrittlement, and the stress corrosion sensitivity in the solution of NH4SCN, NaCl, NariSO4.
