Методом ридж-анализа проведено исследование поверхности отклика, описывающей математическую модель влияния соотношения Al/Mg и температуры на жидкотекучесть Al-Mg сплава при литье под низким давлением. Показано, что на основе математической модели, построенной путем реализации центрального ортогонального композиционного плана (ОЦКП) второго порядка, могут быть найдены субоптимальные значения технологических режимов, обеспечивающих получение максимальных значений жидкотекучести Al-Mg сплава с учетом накладываемых на технологический процесс ограничений
