Cu–Al–Ni shape memory alloys (SMAs) are attractive for structural and functional applications due to their cost-effectiveness and shape memory behavior. This study systematically investigated the effect of beryllium (Be) addition on the phase stability, microstructure, transformation temperatures, mechanical hardness, corrosion resistance, and wear behavior of Cu–Al–Ni alloys. Alloys with Be contents ranging from 0 to 1.5 wt.% were fabricated via arc melting and subjected to thermal treatment. Characterization techniques included dilatometry, X-ray diffraction (XRD), microhardness testing, potentiodynamic polarization, and pin-on-flat wear testing. The results showed that Be additions ≤ 0.4 wt.% stabilized the martensitic β′ phase, while higher concentrations favored the formation of austenitic β phase with a BCC structure. Hardness increased with Be content, especially in austenitic samples. Corrosion tests revealed that while the 0.2 wt.% Be alloy exhibited the most positive corrosion potential (Ecorr), it also had a higher corrosion rate. Overall, corrosion resistance declined with Be concentrations ≥ 0.6 wt.%. Wear tests demonstrated improved resistance in martensitic alloys, attributed to pseudoplastic deformation. These findings highlight the dual role of Be in modifying phase stability and functional properties, offering useful guidance for designing Cu-based SMAs with tailored performance.

Swainsboro High School student-athlete Ja’bios Smith was recently recognized by the Macon Touchdown Club after being named to its Super 7.

The Israel Defense Forces will present a plan to transfer responsibility for civilian law enforcement in Judea and Samaria to the Israel Police, Defense Minister Israel Katz announced on Monday.

The Israel Police opened an investigation on Sunday into the vandalism of Israeli flags near Ateret, in the Binyamin region of Samaria, the force told JNS on Monday.

A 4.2-kilometer (2.6-mile) circular trail along the Tzippori River in the Lower Galilee has been upgraded to improve accessibility for people with disabilities, families with strollers and senior citizens.

The study suggests that Neanderthal man may have retained an ancestral form also found in modern human females, while the modern human male pelvis underwent significant evolutionary changes.

David Israel/TPS-IL Aug 18, 2026 Posted 1 hr ago at 6: 08 AM The Israel Defense Forces confirmed on Monday that it had recovered belongings believed to belong to Maj. Yehuda Katz, who has been missing since a battle in Lebanon in 1982. Katz was one of three Israeli soldiers who went missing following the Battle of Sultan Yacoub on June 11, 1982. The remains of the other two, Sgt. Zachary Baumel and Sgt. Zvi Feldman, were recovered in 2019 and 2025, respectively. Rabbi David Turgeman served in Katz's armored platoon when they drove into a Syrian army ambush that day. By the time Israeli artillery began striking the Syrians and providing relief to the ambushed platoon, Turgeman had already evacuated his tank, he recalled to The Press Service of Israel “I used to think, sometimes I had naive thoughts, when reciting the blessing of the revival of the dead. But no—you have to bless the true and good Judge, so ... so that [Katz will] be brought to burial, God willing. When that happens, I'll come to some kind of closure,” Turgeman told TPS-IL Israel continues to search for two other missing servicemen: Lt. Col. Ron Arad, who was last seen after parachuting from a damaged aircraft over Lebanon on Oct. 16, 1986, and Sgt. Guy Hever, who disappeared from his army base in the Golan Heights on Aug. 17, 1997.
