研究的目的是确定HF-Ti系列的每种合金相对于Zr-2合金和相对于该系列中的其它合金的耐腐蚀性，所述HF-Ti系列的每种合金以10%的步长包含10至90%范围内的钛。将每种合金制成100克纽扣的形式，将其辊压成片材，然后在900 ℃下退火48小时，并切成腐蚀试样，在580 ℉的水中和750 ℉的蒸汽中测试腐蚀试样，两种测试都根据锆腐蚀委员会建立的用于测试锆合金的标准实践进行。结果表明，相对于Zr-2，含10 - 30%钛的Hf -Ti系列合金在热水或蒸汽中不耐腐蚀。他们还指出，对于在水中长达140天和在蒸汽中长达60天的时间段，40 - 50%钛的合金在耐腐蚀性方面通常与锆-2合金相当，而50 - 90%钛的合金在这方面要优越得多上级。在整个范围内，耐腐蚀性随着钛含量的增加而明显改善，尽管对于给定的钛含量增加，改善的量在较高的钛浓度下变得较小。（auth）«少
The purpose of the investigation was to determine the corrosion resistance, relative to that of Zircaloy-2 and relative to that of others in the series, of each alloy of the HF-Ti series comprising, in 10% steps, those in the range 10 to 90% titanium. Each alloy was made in the form of a 100 gram button which was rolled to sheet and then annealed at 900 deg C for 48 hr and cut into corrosion specimens which were tested both in water at 580 deg F and in steam at 750 deg F, both tests being conducted according to standard practice established by the Zirconium Corrosion Committee for testing alloys of zirconium. The results indicated that relative to Zircaloy-2 the alloys of the Hf --Ti series of 10 to 30% titanium are not corrosion resistant in hot water or steam. They indicated also that for time periods up to 140 days in water and to 60 days in steam, the alloys of 40 to 50% titanium are generally comparable in corrosion resistance to Zircaloy-2 while those of 50 to 90% titanium are, in this respect, much superior. Over the entire range, corrosion resistance apparently improves with increasing titanium content althoughmore » the amount of the improvement, for a given increase in titanium, becomes less at higher concentrations of titanium.
