MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641042168 A) filed by Bapatla Surendra Babu; and Irukumalli Priyanka, Tenali, Andhra Pradesh, on April 2, for 'continuous metallurgical fatigue prognosis apparatus exploiting multi-parameter barkhausen noise spectral fingerprinting.'
Inventor(s) include Bapatla Surendra Babu; and Irukumalli Priyanka.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "A continuous metallurgical fatigue prognosis apparatus addresses the high cost and disruption of offline replica testing by actively monitoring in-situ microstructural creep damage. An electromagnetic sensor interface (120) and a magnetization source (130) are permanently affixed to a ferromagnetic steel component (110). As operational stress induces physical creep damage, evolving microstructural pinning sites (220) alter how magnetic domain walls (210) traverse the material. A spectral analysis processor (310) captures the resulting electromagnetic voltage bursts and extracts a multi-parameter BN fingerprint (320) comprising measurable spectral characteristics. A hardware-encoded creep classifier (410) maps these shifts to predefined threshold ranges corresponding to physical Neubauer stages (420). A prognostic logic unit (430) generates a real-time remaining useful life (440) output signal. This provides the objective technical advantage of preventing catastrophic equipment failure and eliminating destructive surface replica testing through continuous electronic tracking of magnetic domain wall motion characteristics."
