The results show that proper RRA heat treatment can improve SCC properties with retention of the high strength of T6 level. After preaging at 100℃for 24 h, retrogression at 200℃for 7 min, and reaging at 100℃for 24 h, the ultimate tensile strength, yield strength and elongation of the alloy are 795 MPa, 767 MPa and 9.1%, respectively. Meanwhile the failure time of the alloy applied to tensile strength of 210MPa in 3.0%NaCl+0.5%H2O2corrosion condition is longer than 720 h. The corresponding TEM observation shows that after retrogression for 7 min and re-aging treatment, the microstructure of grain boundary is similar to that treated in the T73 condition with coarsen and isolated distribution, and the microstructure inside grain is similar to that treated in the T6 condition with small and homogeneous distribution.
研究结果表明:在峰值时效T6状态下合金强度高,但抗应力腐蚀性能差;采用合适的RRA热处理工艺既能使合金保持T6状态下的高强度的同时,又能显著改善合金的抗应力腐蚀性能;经回归7 min RRA处理后合金的晶界类似T73态析出相聚集粗化,而晶内类似T6态析出相细小弥散分布,在拉伸应力为210 MPa和3.0%NaCl+0.5%H2O2腐蚀液中,其断裂时间大于720 h,相应的抗拉强度、屈服强度和延伸率分别为795 MPa, 767 MPa和9.1%,显示优越的综合性能。

It is extremely difficult to solve the problem of tunnel leak, because there are many muddiness, greasy dirts and slushes on the top of the tunnel, thereby it is hard to conglutinate the waterproof materials. Test results show that the impervious pressure and the splice strength of the acrylic acid waterproof material will be up to 1.2 MPa and 1.8 MPa in 30 min with new formula and unique construction craft 50 that reduce the difficulty of conglutination.

The most suitable range of temperature is 25~30℃ and lethal temperature is 56℃ for hypha growth, the most suitable temperature is 25℃ for produce more conidiospore and lethal temperature is 56℃ for conidiospore. Within the pH range of 3~11 the hypha could grow and produce conidiospore. The optimum pH is 5~7 for hypha growth and 3, 9, 10 for produce more conidiospore. The range of glucose concentration is 2%~8% for hypha growth, the most suitable glucose concentration is 2% for hypha growth and produce more conidiospore. The effect of illumination on Bipolaris cynodontis was significance to the growth hypha and spore numbers. The whole light is advantage of hypha growth, but could not produce conidiospore. Alternation of light and darkness for 12 hours is advantage of hypha growth, as well as produce conidiospore.
菌丝最佳生长温度是25~30℃之间,在25℃时最利于产孢,菌丝生长和分生孢子的致死温度是56℃;该菌在pH 3~11范围内均能生长,产生分生孢子,菌丝生长的最适pH 5~7,产孢量最大的pH是3,9,10;糖浓度在2%~8%菌丝能生长,在糖浓度为2%时菌丝生长最好,产孢量最高;光照对病原菌的菌丝生长和产孢有明显影响,在全光照的条件下有利于菌丝的生长,但不会产孢,黑暗12h光照12h既利于菌丝生长又利于产孢,而全黑暗的条件下不利于菌丝生长和产孢。
