Abstract: A low-cost, thermomechanical method for manufacturing [001] textured FeGa alloys is described. The method includes hot rolling a FeGa cast ingot to break down the cast structure, a two-stage warm rolling with an intermediate anneal, and then a final texture anneal that resulted in recrystallization and a recrystallization-induced texture. The FeGa ingot contains a grain growth agent that was used to restrain grain growth of the FeGa material in the undesired crystallographic direction. A protective steel sheath can be placed around the FeGa material during processing to avoid direct contact of the FeGa and the rolls during the hot and warm rolling process steps and also avoid oxidation of the alloy ingot. FeGa alloys with a very strong [001] texture and a large magnetostriction along [001] crystallographic direction were obtained using this method. FeGaBe alloys and new methods for making them are also described.

Abstract translation: 描述了用于制造[001]织构化的FeGa合金的低成本的热机械方法。 该方法包括热轧FeGa铸锭以分解铸造结构，进行中间退火的两级热轧，然后进行最终的织构退火，导致重结晶和再结晶诱导的织构。 FeGa锭含有晶粒生长剂，其用于抑制FeGa材料在不期望的结晶方向上的晶粒生长。 在加工过程中，可以在FeGa材料的周围放置保护性钢护套，以避免在热轧和热轧工艺步骤期间FeGa与辊的直接接触，并避免合金锭的氧化。 使用该方法获得具有非常强的[001]纹理和沿[001]结晶方向的大的磁致伸缩的FeGa合金。 还描述了FeGaBe合金及其制备方法。

Abstract: The sacrificial anode cathodic protection for reinforcing steel in concrete is accomplished and enhanced by mixture control of cementitious material covering zinc or zinc alloy anode. At least 4% lithium hydroxide by weight of the cementitious material is required to prevent the passivation of the zinc anodes after use for many years. The zinc anodes covered by the cementitious material with sand size number about 30 to 60 of US standard sieve provide better uniform current output. Combination of minimum lithium hydroxide and sand size control in the cementitious material will improve the anodes performance and prevent them from passivation.
