Single crystal and directionally solidified casting processes are among the most complex techniques available, requiring stringent process control and a thorough understanding of engineered materials and specialty alloys. This article examines how an aerospace material company utilizes advanced investment casting techniques to create components that meet the increasingly demanding requirements of modern aerospace and gas turbine engines. The article highlights how solidification modeling and integrated computational materials engineering (ICME) have accelerated development processes by predicting material behaviors and optimizing casting parameters without extensive experimental testing.
Cardiovascular disease is the leading cause of pregnancy-related death in the United States. The increasing rates of several cardiovascular risk factors including obesity, sleep apnea, diabetes, hypertension, hyperlipidemia, smoking, and sedentary lifestyle may play a role in the rise in maternal mortality observed in the United States. Maternal risk factors for cardiovascular disease are also associated with increased maternal and fetal morbidity and mortality. For women pursuing pregnancy, addressing these risk factors by screening and treating early may mitigate both peripartum maternal and fetal risks.
