he oxidation and hot corrosion of NiAl-20Fe alloy at 850 ̄1150℃ and 850 ̄950℃ respectivelywere studied. It was shown that both oxidation and hot corrosion of the alloy obey the parabolic ratelaw. The addition of 20at% Fe to intermetallic compound NiAl caused a little drop in oxidation resistance,but a great decrease in resistance against hot corrosion. Compared with NiAl-30Fe, due to a decrease inFe content, an increase in Al content and the addition of Y and Ce, the NiAl-20Fe alloy showed someimprovements in...

Compared with FeCrAl alloy, Fed15Cr-4Al-Y alloy has lower brittleness (at high temperature and 475 ℃ ),higher heat-resisting strength and better machinability,with the high operating temperature and good anti-oxidation of FeCrAI being retained. Pe-20Cr-4Al-Y and Fe-25Cr-4Al-Y alloy with higher operating temperature have been developed, so that low brittle alloy series have been set. Addition of strengthening elements can further improve heat-resisting strength; while light rare-earth elements can reduce the...

Compared with FeCrAl alloy, Fed15Cr-4Al-Y alloy has lower brittleness (at high temperature and 475 ℃ ),higher heat-resisting strength and better machinability,with the high operating temperature and good anti-oxidation of FeCrAI being retained. Pe-20Cr-4Al-Y and Fe-25Cr-4Al-Y alloy with higher operating temperature have been developed, so that low brittle alloy series have been set. Addition of strengthening elements can further improve heat-resisting strength; while light rare-earth elements can reduce the production cost instead Of Y. The alloy series can be used in electroheating, resistance element, heat-resisting components and high temperatare coat. It can reduce cost and improve operating temperature and service life instead of Ni-Cr alloy series.

Fe-15Cr-4Al-Y合金克服了FeCrAl合金的高温脆化和475℃脆性,热强性和冷加工性也明显改善,FeCrAl使用温度高,抗氧化性好等优点则得到保留。还研制了使用温度更高的Fe-20Cr-4Al-Y,Fe-25Cr-4Al-Y合金,形成了低脆性合金系列。加入强化元素能进一步提高合金的热强性.用轻稀土元素代替Y则能降低生产成本。该低脆性合金系列可用于电热、电阻元件、耐热结构件和耐高温涂层.用它代替Ni-Cr系合金可降低元件成本,提高其使用温度和服役寿命.

It was indicated that,according to studies on microstructures and properties,Fe-(8~40)Ni-(10~30)Cr-(3~8)Al alloys with 0.02~0.08wt% RE possessed outstanding oxidation-resistance and quite high hot strength.The highest hot strength,plasticity,embrittlement-resistance,cold-workability and weldability,which were higher than or close to those in Cr20Ni80alloy,were found in several γ-phase alloys.When structure in the alloys became γ+α double phase,the strengh and hardness increased and the plasticity decreased...

It was indicated that,according to studies on microstructures and properties,Fe-(8~40)Ni-(10~30)Cr-(3~8)Al alloys with 0.02~0.08wt% RE possessed outstanding oxidation-resistance and quite high hot strength.The highest hot strength,plasticity,embrittlement-resistance,cold-workability and weldability,which were higher than or close to those in Cr20Ni80alloy,were found in several γ-phase alloys.When structure in the alloys became γ+α double phase,the strengh and hardness increased and the plasticity decreased considerably,so the cold-workability lowered.However,a satisfactory weldability remained in the double phase alloys.Extremely high strength and hardness and very low plasticity existed in α-phase alloys,which could not be cold worked almost.

从Fe-(8~40)Ni(10~30)Cr-(3~8)Al合金中筛选出3种γ相合金,它们的抗氧化性与FeCrAl合金相同,热强性、抗脆化能力和塑性与Cr20Ni80合金相当,而且有良好的铸造、冷加工和焊接性能,热加工工艺已被掌握。合金生产成本为Cr20Ni80的1/3,在耐热和电热领域有重要的应用前景。选出了2种γ+α双相合金,与FeCrAl合金相比,其抗氧化性相同,热强性和抗脆化能力略高,塑性稍低,可用于高使用温度耐热结构元件。α相合金塑性很低,但可从它极高的强度和硬度特性开发实际应用。添加稀土元素对发展新合金起关键作用。
