The following reactions have been proposed:Because the above reactions pick up residual carbon in γ-matrix, the formation of M6C and M23C6 is restricted.Besides, large quantity of niobium containing in MC carbide of K19H mates MC stabilize, therefore slows down the following reaction

Systematic experimental studies on the damaging effect of pressure wavesof more than 20 kinds of weapons were performed in,about 2000 guinea,pigs ex-posed under various conditions.The results showed that within a very wide wea-pon spectrum the damaging effect of the pressure wave was exerted chiefly on themiddle ear structures and on the inner ear.No sign of central auditory impair-ment could be found even when the peak pressure of the explosion wave was ashigh as 190 dB SPL.The degree and characters of the injury were closely related to the intensityof the pressure wave,but the damaging effect on the middle ear and that on thecochlea were by no means parallel.When the peak pressure of the wave was veryhigh,damage was likely to occur only or mainly in the middle ear structures whilethe inner ear seemed more susceptible to wave of moderate peak pressure of longimpulse duration for a large number of rounds.In certain exposure conditionsdestruction of the sound transmitting system of middle ear by the first few shockswould somehow buffer the lashing of the waves of the succeeding firings at thecochlea,thus reducing its damaging effect.For pure middle-ear blast injury or for mixed trauma of both the middle andthe inner ear,hearing loss in guinea pigs does not show marked high-frequencyselectivity,as this is usually seen in cases of noise-induced deafness in human sub-jects where the inner ear is often the main site of damage.

本工作用二十余种武器压力波源在不同暴露条件下对近二千只豚鼠进行了系统的致伤实验。结果表明,压力波暴露后致伤部位主要在中耳和内耳;即使压力峰值已高达190dBSPL,听觉中枢还未见有损伤迹象。中耳损伤和内耳损伤的程度都与压力波的强度有关,但两者并不平行,压力峰值大时压力波可以只损伤或主要损伤中耳,压力峰值不很大但重复发数较多或脉宽较大时,则可能只损伤或主要损伤内耳。在一定的条件下,中耳的损伤能缓冲压力波对内耳的冲击,从而减轻内耳的损伤。在中耳损伤或中耳、内耳混合损伤时,豚鼠的听力丧失并没有象在人的噪声性耳聋时(内耳损伤为主)常见的那种突出的高频选择性。

It has been proved that most of the titanium alloys are susceptible to the so-called hot salt stress corrosion cracking under the combined action of high temperature, halide salt and stresses.In this paper the susceptibility of hot salt stress corrosion cracking of titanium alloy Ti-679 was investigated in the temperature range of 350~500°C.Experimental studies show that the microstructure of the alloy has pronounced effect on the susceptibility of H.S.S.C.C.It was shown that the threshold stress for H.S.S.C.C.of...

It has been proved that most of the titanium alloys are susceptible to the so-called hot salt stress corrosion cracking under the combined action of high temperature, halide salt and stresses.In this paper the susceptibility of hot salt stress corrosion cracking of titanium alloy Ti-679 was investigated in the temperature range of 350~500°C.Experimental studies show that the microstructure of the alloy has pronounced effect on the susceptibility of H.S.S.C.C.It was shown that the threshold stress for H.S.S.C.C.of the specimens with α+β annealed structure was higher than that of the specimens with β annealed structure under the same hot exposure conditions.Experimental results also proved that the threshold stress of the specimens with compressive stress on the surface was higher than that of the specimens without it.Ion microprobe scanning analyses on the fractured surface showed that hydrogen was greatly concentrated at the crack surface and that hydrogen produced during the stress corrosion of titanium alloy by halide salt and subsequently absorbed by the alloy was responsible for cracking.

在350~500℃范围内研究了Ti-679合金的热盐应力腐蚀性能。实验表明合金的显微组织对热盐应力腐蚀的敏感性有很大的影响,在相同的热暴露条件下α+β相区热处理试样的临界应力比β相区热处理的要高。试验结果也表明,表面存在压应力的试样的临界应力高于无压应力者。用离子探针对断口表而进行的测定显示出在裂纹中有氢的大量富集,这表明钛合金在受热盐应力腐蚀过程中所产生的并随后被吸收的氢是开裂的主要原因。
